Bug#187091: gcc-3.2: restrict is broken in C99 mode



Package: gcc-3.2
Version: 1:3.2.3-0pre6
Severity: normal

When I compile certain files (a testcase is attached), gcc fails to
compile with the following error:
broken-restrict.c:25: invalid use of `restrict'
I am sure this is a valid use of restrict because I have seen it used in
<http://www.opengroup.org/onlinepubs/007904975/functions/lio_listio.html>
(SUSv3), which is aligned with C99. In fact, that page says, in part:

	The restrict keyword is added to the lio_listio() prototype for
	alignment with the ISO/IEC 9899:1999 standard.

It also fails to compile with the snapshot (with the same error).

You can compile this with:
"gcc -std=c99 -c broken-restrict.c" and it will break or you can use
"gcc -DRESTRICT_IS_FUCKED -std=c99 -c broken-restrict.c" and it will
work.

I've pretty much narrowed it down to the restrict in the brackets (if
you put them on a new line, you will see that they are the cause of the
syntax error).
